TopN + other values

[Anonymous]

Hello,

I'm trying to create a topN + other values table. As a simple example, i have a table that looks like this:

customer	amount
A	1
B	2
C	3
D	4
E	5

and i would like to have a table that produces the following result, for a selected value of TopN (for example N = 3)

customer	amount
E	5
D	4
C	3
Others	3

Note that "Others" represent the sum of everything else that isn't in top 3

I am able to get the Top 3 table, as well as the value of Others through a new measure separately with the formula 

other calculation = CALCULATE([amount],topn(2, values(Sheet1[customer]), [amount],1))

but i don't know how to merge the two into a single table. Any help would be appreciated, thanks!

Hi @Anonymous 

To calculate Others you will need to create a Column with the expression like below.

Rank Top 3 Products and Others = 
-- add this column to your customer table
VAR rnk = RANKX(
    'Product', -- replace with customer table
    CALCULATE(SUM(Sales[Quantity])),,, -- amount column
    Dense
) <= 3
RETURN 
IF(rnk, FORMAT('Product'[Product Code], ""), "Others") -- replace Product Code with Customer

Thank you for your help! The code worked perfectly, but i just have some questions about the code itself for better understanding,

In the "Rank Top 3 Products and Others" code, what is the purpose of the FORMAT code?

In the "Rank Top Three Sales" code, why do you need the IF statement after RETURN if there is no ResultIfFalse?

Thank you.

Hi @Anonymous 

FORMAT(123 ,"") will return 123 as text.
IF without third argument will produce BLACK , when added to a visual it will produce only top 3.

Hope this helps

HI @Anonymous,

You can use the expresion below.

Rank Top Three Sales = 
VAR rnk = RANKX(
    CALCULATETABLE(
        VALUES('Product'[Brand]), --Replace with your customer 
        ALLSELECTED()
    ), 
    [Sales],, --Replace with your amount 
    DESC
) <= 3
RETURN IF(rnk, [Sales]) --Replace [Sales] with your amount
